Cummins DOC OEM Equivalent

The Roadwarrior C0152-ID is a premium Diesel Oxidation Catalyst (DOC) engineered as a direct-fit OEM equivalent for Cummins part number 4353264. Designed to meet or exceed original factory specifications, this high-performance component is the ideal solution for fleet managers and mechanics who demand reliability without the premium OEM price tag. At the heart of the C0152-ID is Roadwarrior’s innovative Metalcor® catalyst technology. This advanced coating maximizes passive regeneration throughout your drive cycle, significantly reducing the frequency of forced active regens. By maintaining lower back pressure even under high-load conditions, this DOC helps restore lost fuel efficiency and reduces the consumption of both diesel and Diesel Exhaust Fluid (DEF). Beyond emissions compliance, a healthy aftertreatment system is vital for engine longevity. By installing a high-quality replacement like the C0152-ID, you prevent the ECU from overcompensating for worn components, which often leads to decreased power and increased EGR rates that can harm engine health. Installation is streamlined thanks to the precise direct-fit design, ensuring your heavy equipment spends less time in the shop and more time on the road. Trust Roadwarrior to deliver the durability and efficiency required to keep your Cummins engine running at peak performance.
